CAE SUSTAVI

Skraćenica od Računalom podržano inženjerstvo (Computer - aided engineering). To su računalni sistemi koji analiziraju inženjerske dizajne. Većina CAD (računalom podržano dizajniranje) sistema ima CAE komponentu, ali tu su isto i nezavisni CAE sistemi koji mogu analizirati dizajne napravljene različitim CAD sistemima. CAE sistemi su u mogućnosti simulirati dizajn pod mnogobrojnim uvjetima da vide ...view middle of the document...

Tipični CAE program je napravljen od broja matematičkih modela enkodiranih algoritmima napisanih u programskom jeziku. Prirodni fenomen koji se analizira je predočen pomoću inženjerskog modela. Fizička konfiguracija je predočena pomoću geometrijskog modela. Rezultati, zajedno sa geometrijom, su vidljivi preko korisničkog sučelja na ekranu računala i preko slike. Sustavi za Računalom podržano dizajniranje i proizvodnja su kreirani od strane svemirske industrije u ranim 1960-ima da bi pomogli u masivnom dizajnu i dokumentacijskim zadatcima povezanim sa proizvodnjom zrakoplova. CAD/CAM sustavi su prvenstveno korišteni za detaljno dizajniranje i crtanje zajedno sa generiranjem numeričkih linija koda za proizvodnju. Postepeno više CAE funkcija je dodavano CAD/CAM sustavima modeliranje sa CAD/CAM sustavima je postalo prilično sofisticirano. Najpopularniji komercijalni sustavi podržavaju 2D i 3D mreže, površinske modele i čvrste modele. Za čvrste modele koristi se kombinacija tri tipa prikaza: konstruktivna čvrsta geometrija, granični prikaz i prikaz pregleda.
CAE metode za električno i elektroničko inženjerstvo su vrlo razvijene. Geometrija je općenito dvodimenzionalna, a problemi su većinom linearni ili mogu biti linearizirani sa dovoljnom točnošću. Kemijsko inženjerstvo koristi opsežnu upotrebu CAE sustava sa simulacijom procesa i kontrolnim programima. Arhitekturalno korištenje CAE sustava je slično inženjerskom korištenju samo sa naglasom na arhitekturi. Svemirsko, strojarsko, industrijsko i proizvodno inženjerstvo koriste strojarski CAE softver zajedno sa specijaliziranim softverom.

CAD MODELI
CAD SOFTVER
CAD softver se koristi za crtanje ahitektonskih i inženjerskih crteža i za izradu tehničkih ilustracija svih vrsta. CAD vam omogućava da pripremite brze i precizne crteže. Omogućava fleksibilnost za izmjenu crteža uz minimalan trud. U proteklim godinama, mnogi profesionalci su prešli na CAD da uživaju u prednostima ovog preciznog i kreativnog alata. Danas, mnoge edukacijske ustanove koriste CAD kao dio njihovog akademskog rasporeda. Kao rezultat, CAD znanje je postalo vrlo važno svim profesionalcima uključenim u polje dizajna i crtanja. To je korištenje računalnog softvera i sistema za dizajniranje i stvaranje 2D i 3D virtualnih modela i proizvoda u svrhu testiranja. To se nekad zove i računalom podržano crtanje.
CAAD SOFTVER
Računalom podržana arhitektura se vrlo kratko koristi, razlog ovome je sto su arhitekti sporo usvajali mogućnosti računalne tehnologije. Jedan od razloga je cijena ovih sustava. Računalom podržan arhitekturalni dizajn softveri su repozitorij točnih i iscrpnih crteža zgrada i koriste ih arhitekti i ahitektonske tvrtke. Prvi program je instaliran 1960-ih kako bi pomogao arhitektima da uštede vrijeme crtanja crteža. Prvo se koristio CAD, ali kako nije mogao ponuditi sve alate koje su arhitekti trebali za izvršavanje projekta razvijen je CAAD kao posebna vrsta softvera.
